To all whom it may. concern:

Be it known that I, EDUARDO Josn MARIA 1 MADERO, a citizen of the Argentine .Re-

p I the other disk will be moved into position mounted in each public, residing at Buenos Aires, Argentina, have invented new and useful Impr'ovements in Rotary Engines, lowing is a specification.

The invention consists in constructing an annular piston-cylinder of two semi-circular bodies connected at their ends by two transversely arranged circular, dished plates, each pair of opposed plates forming a chamber intersecting the cylinder at diametrically opposite points of the latter. An obturating disk or valve is rotatably chamber and suitable gearing, actuated by the movement of the plston in the cylinder, is provided for simultaneously rotatingthe disks, whereby a' solid art of one disk and a cutaway portion of to close the cylinder behindthe piston and open it in front of the same.

fly wheel, the

The piston is carried by a periphery of which constltutes a section of the cylinder, and the admission and exhaust passages for the driving medium are located within the fly wheel and open into the cylinder in close proximity-to both ends said grooves and of the piston.

Both faces of the obturating disks and of the fly wheel are formed with a series of circumferential grooves which register with sets of similar groovesin the plates forming the chambers and in covers arranged on both sides of the fly wheel, whereb a certa1n amount of steam is condense within operates to effect a tight fitting of the parts without loss of'energy by frlction.

For the ready understanding of this-descrlption, illustrative drawings have been I annexed .thereto, in which:

the lineA-B of Fig. 3, of tion of the adjusting plates 01'' covers with the driving wheel .and the circular chamber-or casing. V.

In said drawings, semi-circular parts or I pointsof connection are formed the plates 2 and which after bein connected together by means ofbolts 3, orm the circular:cas-

1 in dicatesfthe hollow ing of the annular piston-cylinder and valve chambers. Y

Said casing has an annular opening, covered b the periphery of the flier or driving w eel 4, provided with grooves according to the diameter of the obturating disks hereinafter described. The sides of said wheelfare formed with a series of cirthe cornbinabodies at whose.

cumferential grooves 5 arranged to register with other sets of grooves 6', formed in similar number and diameter, on ternal faces of the adjusting plates-6..

These latter plates are provided on their with two grooves, filled with any suitable packing material in order to obtain a perfectly tight fitting between said plates and the casing. According to this arrangement, the casing itself and the lateral plates -or covers form with regard which the adjustment maybe regulated bymeans of the lateral screws 7 by which thesaid plates may be moved to the desired extent. I

In order to maintain in a concentric position with regard to the casing, radial arms 10 are employed,

ess diameter,

mounted at both sides and constructed of two detachable parts, arranged in. such a manner as to render their position unalterable. At the point where-said arms meet, are inserted the bearings ,9.

The bearings 9 are of the common steel ball bearing type combination with the bearings 11 which allow of regulating the axial position of the fiy-wheel with regard tothe casing.

- On the periphery of the fly-wheel 4 is plunger 12 which carries two pac ng ring obturating disks.

By referring to Fig. 3, it will be seen the ins 13 of a width somewhat greater than the thickness of the 'eripheries and on their stepped parts of the driving wheel I 4 and support the axle in pipes 14., which pass through the in terior of the fly-wheel and are alternately employed for the admission and exhaust of with the hollow axle 16 and with the pipe 17 which passes through the interior of the same, In the present case, the said axle,

16 is shown as exhausting into the air while the pipe 17 applies its orifice to the periphery of the axle, being combined with a sleeve 18 to which is connected the steam pipe (not shown). Said sleeve allows of the entrance of steam every time the orifice of the pipe 17 registers with the inlet 18' in the sleeve, to which end the admission must be combined with the movement of the plunger.

The plates or covers 2, when connected together, form chambers in which are placed and move the obturating disks 19 and 20. These disks, diametrically arranged one at each side of the casing, are secured to the respective axles 21, mounted at both ends in pairs of steel ball bearings 22 and 23, operating respectively in a longitudinal and transverse sense with regard to the axle.

At each side of the disk is mounted a vplate 24, on the internal face of which are approach the obturating disk by means of formed circular grooves 25 eccentric to the axle of the disk and cooperating with grooves 19 on the disk concentric to the axle which assist in obtaining a better fitting with the disk. Said plates are caused to the screws 26, so that the adjustment or fitting between both parts may be carried out to the desired extent.

As has already been stated when describing the plates or covers 6, the condensation of steam within the circular grooves permits of a perfectly tight fitting being obtained without any friction being caused between the surfaces.

Each axle 21 carries a helicoidal toothed wheel 27 which meshes with another similar wheel 28, keyed to the axle 29, maintained in position by the bearings 30 and driven by the helicoidal gear wheel 31 which meshes with another similar wheel 32, of same diameter and keyed to the main axle 8.

Owing to this arrangement, the number of turns performed by theplunger is exactly the same as that effected by the obturating disks.

The combination of motion between the plunger and the disks is such that in whatever direction the engine be running, at the moment in which the plunger is about to pass by the point where one of the disks is placed, this latter will present its cut away part to the annular chamber of the casing naeaeos and thereby permit of the passage of the plunger, while the opposite disk will keep the annular chamber closed till in its turn, it is obliged to clear the latter.

The operation of the engine is as follows: Supposing the plunger to be in any position, as for instance that shown in Fig. 3, at the moment of admitting steam by the pipe 17, the same will pass through the pas-' Owing to the manner of combining the movement of the obturating disks with that of the plunger and to the fact that in this latter, the point of initiation of said movement is, on one side, the admission of steam, and on the other, the exhaust, no dead point occurs in the operation of the engine, whichever be the position in which the engine is started, in one or the other direction. It will further be evident that as all movements of the engine are rotary, the same may be run at low or high speed without causing vibration and without any of, its operative parts being liable to fracture, such as high speed will cause in ordinary engines.

As has already been stated before, the motive power developed by the engine is constant through the entire stroke or revolution of the plunger if the admission of energy is effected without interruption, but if the engine be desired to operate partly by energy and partly by expansion of the same,

it will be necessary to obturate the admiswhic may readily be obtained by any suitable valve arrangement, as has been described before or by means of any other convenient type.

Steam pressure or fluid pressure obtained by the combustion of gases may as well be employed for conveniently operating the engine.
